Yes, your findings are also very strange.
I wonder if we can discover the "inventor" of all this and ask him
how it should work or better how he originally wanted it to work.
Comments in the code (RebalanceLeaders.java) state that it is possible
to have more than one electionNode with the same se
We are running a solr cloud cluster using solr 7.4 with 8 shards. When we
started our solr cloud with a zookeeper node (without collections directory
but with only solr.xml and configs) our data directory containing
core.propery and cores data becomes empty.

How to know attributes like shard name and hash ranges with associated core
names if we lost state.json file from zookeeper.
core.properties only contains core level information but hash ranges are
not stored there.
Does solr stores collection information, shards information anywhere.

Have you lost dataDir from all zookeepers?
If not, first take a backup of remaining dataDir and then start that zookeeper.
Take ZooInspector to connect to dataDir at localhost and get your
state.json including all other configs and setting.

Solr doesn't just remove directories, this is very likely
something in your environment that's doing this.
In any case, there's no information here to help
diagnose. You must tell us _exactly_ what steps
you take in order to have any hope of helping.

How did you "lose" the data? Exactly what happened?
Where does the dataDir variable point in your
zoo.cfg file? By default it points to /tmp/zookeeper,
which can be deleted by the op system when
the machine is restarted.
Otherwise you can get/put arbitrary znodes by
using "bin/solr zk cp". Tr
Not a direct solution, but manipulating data in Zookeeper can be made
easier with https://github.com/rgs1/zk_shell

This sounds like something that might crop up if the admin UI were exposed
to an alternate (or public) network space through a tunnel or proxy. The
server knows nothing about the proxy/tunnel, and the cloud page has nice
clickable machine names that point at the internal dns or ip names of the
node
Executive summary:
The central problem is "how can I insert an ephemeral node
in a specific place in a ZK queue". The code could be much,
much simpler if there were a reliable way to do just that. I haven't
looked at more recent ZKs to see if it's possible, I'd love it if
there were a better way.

We've seen the same thing on solr 7.5 by doing:
- create a collection
- add some data
- stop solr on all servers
- delete all contents of the solr node from zookeeper
- start solr on all nodes
- create a collection with the same name as in the first step
When doing this, solr wipes out the p
Thanks for the information Erick –
I’ve learned there are 2 ‘classes’ of documents being stored in this collection.
There are about 4x as many documents in class A as class B.
When the documents are indexed, the document ID includes the key prefix like
‘A/1!’ or ‘B/1!’, which I understand spreads

No. The replicas are in a "down" state the Solr instances

even that wouldn't move all the replicas to the one remaining
node).

You have to check if both of settings are using the same configurations,

Also, the query performance might be affected if there is indexing going on
